react-admin:如何在Edit视图中用代码覆盖字段的值？

import React, { useState } from 'react';
import { Edit, SimpleForm, TextInput, FormDataConsumer } from 'react-admin';

const CustomEdit = (props) => {
  const [customFieldValue, setCustomFieldValue] = useState('');

  const handleCustomFieldValueChange = (event) => {
    setCustomFieldValue(event.target.value);
  };

  return (
    <Edit {...props}>
      <SimpleForm>
        <TextInput source="name" />
        <FormDataConsumer source="customField">
          {({ formData }) => (
            <TextInput
              source="customField"
              value={customFieldValue}
              onChange={handleCustomFieldValueChange}
            />
          )}
        </FormDataConsumer>
      </SimpleForm>
    </Edit>
  );
};

export default CustomEdit;
